Understand the concept of immune responses: The immune system has different types of responses to pathogens, primarily categorized into primary and secondary immune responses.
Define primary immune response: This is the body's initial response to a pathogen, characterized by the activation of naive B and T cells. It typically takes longer to develop and is less robust.
Define secondary immune response: This occurs upon re-exposure to the same pathogen. Memory B and T cells are activated, leading to a faster and stronger response compared to the primary immune response.
Compare the strength of the responses: The secondary immune response is generally stronger and more rapid due to the presence of memory cells that were generated during the primary response.
Clarify the concept of self-tolerance: Self-tolerance is not an immune response to pathogens but rather a mechanism to prevent the immune system from attacking the body's own cells. It is crucial for preventing autoimmune diseases.
